C9300-24S-M Switch

1. SKU Definition

Cisco Catalyst 9300 base non-X chassis, 24×1G SFP fiber non-PoE stackable L3 enterprise switch with modular rear uplink slot; -M suffix = Meraki Cloud-Managed Catalyst variant, subscription-based term licensing (Enterprise/Advanced tier options), global universal AC power supply, managed via Meraki Dashboard cloud orchestration instead of standalone perpetual E/A license model

• S: 24 hot-pluggable 1000BASE SFP downlink slots, supports all Cisco GE SFP optics (SX/LX/ZX/BiDi), no RJ45 copper ports, zero PoE inline power capability
• No X: Standard C9300 hardware with StackWise-480 (480Gbps per-stack backplane), UADP2.0 forwarding ASIC, non-upgraded StackWise-1T platformCisco
• -M: Meraki Cloud Managed platform, IOS XE OS + Meraki cloud management architecture; all software features run on annual/3/5/7/10-year subscription licensing (two tiers: Enterprise & Advanced), no factory pre-installed perpetual Network Essentials/Network Advantage permanent license like -E/-A models

2. Product Overview

Cisco Catalyst C9300-24S-M is a 1U rack-mount stackable Layer3 fiber aggregation switch, dual-manageable via local IOS XE CLI or centralized Meraki Cloud Dashboard. Designed for inter-building fiber campus aggregation, remote closet fiber convergence and branch core deployment beyond 100m copper transmission range. Supports StackWise-480 physical stacking and StackPower+ cross-chassis power pooling for redundant power sharing across stacked units.

Port & Power Specifications

• Downlink: 24×Gigabit SFP slots for flexible fiber transceiver installation; no PoE power budget, no endpoint inline power output
• Rear single modular uplink slot compatible with official C9300 uplink modules: C9300-NM-8X (8×10G SFP+), C9300-NM-4Y (4×25G SFP28), C9300-NM-2Q (2×40G QSFP+), scalable uplink bandwidth up to 40Gbps for future network upgradeCisco
• Default factory pre-install single PWR-C1-715WAC-P-M universal AC power supply; second hot-swappable redundant 715WAC PSU optional for full power redundancy; idle power consumption ~84.6W, max full-load ~124.3W

Core Hardware Performance Parameters

• Wire-rate standalone IPv4/IPv6 forwarding rate: 359 Mpps; maximum full-stack aggregated forwarding rate:718 Mpps
• Stacking: StackWise-480 technology, up to 8 identical C9300-M series switches stacked into single logical switching entity; NSF/SSO <50ms non-stop forwarding failover for high availability
• System hardware: Multi-core processor, 8GB DRAM +16GB onboard flash memory, three variable-speed hot-swappable hot-plug fans; embedded Catalyst 9800 wireless controller for centralized AP management
• Forwarding table resources:
  MAC address table:96,000 entries; IPv4 route table:96,000 entries; IPv6 route table:48,000 entries; Multicast route table:24,000 entries; Jumbo frame up to 9198 Bytes; shared packet buffer for burst traffic schedulingCisco

3. Two-Tier Subscription License for C9300-M (Cloud Subscription Only)

All feature entitlements rely on term-based Meraki subscription license (1/3/5/7/10-year), split into Enterprise & Advanced tiers; license tier upgrades unlock premium functions via cloud authorization remotely
